CLEMENS TO KENTRUP, OF EXELAND, VTISCONSIN.

VEHICLE LOCK.

Application filed July 6, 1922.

T 0 aZZ whom it may concern:

Be it known that I, CLnMnNs TO KEN- nor, a citizen of the United Statesof America, residing at Eireland, in the county of Sawyer and State oflVisconsin, have invented new and useful Improvements in Vehicle Locks,of which the following is a specification.

The object of the invention is to provide a simple and efiicient lockfor Vehicles of the motor driven type and particularly to provide adevice for this purpose which opcrates by cutting 01f the supply of fuelsuch as gasoline; and with this object in view the invention consists ina construction and combination of parts of which a preferred embodimentis shown in the accompanying drawings, wherein Figure l is a view of alocking apparatus embodying the invention applied in the operativeposition to a vehicle.

Figure 2 is a plan view of the same.

Figure 3 is a sectional view thereof.

Fig. 4c is a diagrammatic view showing the relation of the electromagnetto the valve operating means.

The device consists essentially of a spring closed fuel valve '10 whichmay be of any suitable type but which in the construction illustrated isprovided with a normally acting closing spring 11 and which is arrangedin the fuel feed line 12 between the reservoir or tank 13 containing thesupply of fuel and the carbureter 14:, with the usual or any ordinaryoperating stem or spindle 15 which is accessible to the operator and maybe turned to open the valve which is normally held closed. In theconstruction illustrated the stem is provided with a grip or hand hold16, and related with the stem is a combination locking device 17 of anyconventional type serving to prevent the turning of the stem to open thevalve until the proper combination has been set through the adjustmentof an index member 18 serving to adjust the tumblers 19 in the lockcasing. It will be understood that the specific construction of the lockmechanism formsno part of the present invention and that any suitable orconventional form of locking means serving to prevent the turning of thevalve stem may be employed in this connection, but preferably tlelocking Serial No. 573,112.

means should be such that when the valve stem turns to its valve closingposition, the

combination is broken or disarranged so that a manual setting thereof isrequired in order to permit of again turning the stem to open the valve.

In an electrical circuit 20 which includes the ignition generator 21 ofthe vehicle is arranged an electro-magnet 22 and carried by the valvestem is anarmature 23 for attraction by the electro-magnet when thegenerator is in operation.

/Vith this construction it is necessary that the motor be running andtherefore that the generator be in action in order to energize theelectro-magnet and attract the armature so as to hold the valve stem ina position to maintain the fuel feed valve open. As soon as the motorstops and therefore the operation of the generator ceases theelectro-niagnet becomes deenergized and releases the armature so thatthe valve closes and cuts oil the supply of fuel. Obviously there may bea small residue of fuel in the carbureter which will prove to besufficient to start the motor but it will be sufficient only to carry itfor a short distance and not adequate to permit of the continuousrunning of the car.

In order to start the car it is necessary after setting the combinationin order to release the valve stem, to hold the valve by means of thegrip 16 in an open position until the motor starts and actuates thegenerator so as to produce a current sufficient to cause theelectro-magnet to attract and hold the armature and thus maintain thevalve in an open position. The parts will then remain in runningcondition until the operation of the motor ceases whereupon the valvestem will be released as above indicated.

Having described the invention, what is claimed as new and useful is 1.A vehicle lock having a fuel valve yieldingly held in its closedposition, a combination lock mechanism for normally preventing theopening movement of the valve, and means under the control of thegenerator of the vehicle ignition system for holding the valve in itsopen position.

'2. A vehicle lock having a fuel feed valve yieldingly held in itsclosed position, a combination lock mechanism for normally preventingthe opening movement of the valve, and means under the control of thegenerator of the vehicle ignition system for holding the valve in itsopen position and consisting of an electro-magnet in circuit with thegenerator, and an armature carried by the valve and exposed to theinfluence of the electr0-magnet When the valve is in its open position.10

In testimony whereof he afiixes his signature.

CLEMENS TO KENTRUP.
